Abstract

We prepared GeS2-Sb2S3 chalcogenide glasses and investigated the compositional dependence of their linear and nonlinear optical properties. The results showed that large variation range of optical bandgap, linear refractive index, volume of structural nano-voids, and nonlinear optical response (n2 and β) was achieved within this sole glass-forming region. The role of Sb2S3 addition in these properties was also discussed from the microstructural view. It would be of reference significance for comparing or selecting chalcogenide glasses with suitable optical properties for applications in infrared spectral region..
